Question

Define snell‟s law of refraction.​

Answer 1

Answer:

Snell's law :  According to the Snell's law of refraction , the ratio of sine of angle of incidence to the sine of angle of refraction is constant for a given pair of media .

Refractive index =   sine of the angle of refraction /sine of the angle of incidence

​

Answer 2

Snell's law is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.
